The realization of scene effects on LED sky screens mainly depends on their unique working principles and composition structure. The following are the main steps and principles for achieving scene effects on LED sky screens:

LED lighting principle: The LED ceiling screen is composed of a large number of LEDs. When the positive pole of the LED is connected to a positive voltage and the negative pole is connected to a negative voltage, electrons begin to flow. In semiconductor materials, electrons and holes meet and generate energy, which is released into photons, forming visible light. By controlling the current, LEDs can emit light of different colors.

Dot matrix arrangement and control: The LED sky screen is composed of many LED dot matrices, each containing several LEDs. These LEDs are arranged on the screen according to certain rules, forming an array of pixels. LED screens require a control circuit to control the on/off status of each LED, as well as adjust its color and brightness. When the control circuit receives the input image or video signal, it will control the brightness and color of the corresponding LED based on the content and display requirements of the signal.

Scene content display: By changing the brightness and color of each LED, the LED sky screen can present a rich and colorful image and video content. For the sky curtain projection system, it can use seamless splicing technology to place the projection screen on the entire indoor dome, combined with the sound system and lighting system, to form a grand, super large, and realistic projection image. LED sky screens can not only display static images, but also display dynamic videos and other special effects, creating various scene effects.

Customization and interactivity: The scene effects of LED sky screens can also be customized according to specific needs. For example, unique animations, patterns, or texts can be designed based on different scenes, events, or festivals to create a corresponding atmosphere. In addition, LED sky screens can also interact with the audience, such as detecting their movements or sounds through sensing devices, thereby changing the displayed content and enhancing the audience's sense of participation and experience.

In summary, LED sky screens achieve rich and colorful scene effects through their unique lighting principles, dot matrix arrangement and control methods, as well as customization and interactivity. These effects not only enhance the visual experience of the audience, but also enhance the atmosphere and attractiveness of the event.
